03ws with OL3 RNA

GROMACS version: 2024.1
GROMACS modification: No
Dear all,
I am wondering if there is a way to use ff03ws for protein and OL3 for RNA?
I want to compare the behavior and structure of my protein with and without RNA, and my protein-only simulations have done with ff03ws. As I know, the RNA force field bundled with ff03ws is not reliable. Thanks in advanced.

You can use gromologist to explicitly list parameters from different forcefields in your simulation (refer to this post for more details)
